摘要
文章简要介绍了卫星影像及地理空间信息获取技术,对比分析了光学影像及SAR等卫星影像的几何特性和辐射特征,提出了若干有益的见解,并对如何从各种卫星影像中获取地理空间信息的方法进行了总结。
The capturing techniques of satellite imagery and geographical spatial information are in- troduced briefly. And then the geometrical and radiation characteristics of satellite images are analyzed in detail, such as optical images and SAR images. The methods of obtaining geometrical positions of objects in images are summarized.
